Email Domain Health Check

Apne MX, SPF, DKIM aur DMARC records paste karein aur har problem ke fix ke saath score wali deliverability report payein — aapke device par jaanchi jaati hai, kabhi upload nahi hoti.

Email Domain Health Check poori tarah aapke browser mein chalta hai. Paste kiye records aapke device par analyse hote hain — koi DNS lookup nahi hota aur kuch upload ya store nahi hota.

Email Domain Health Check ke baare mein

Email Domain Health Check wo DNS records padhta hai jo tay karte hain ki aapke domain ka mail inbox mein jaayega ya spam mein, aur unhe grade deta hai. dig ya nslookup ka output, ya koi bhi zone-file lines paste karein — tool khud MX, SPF, DKIM, DMARC, MTA-STS, TLS-RPT aur BIMI ko alag kar leta hai. Har record ko uski specification se validate kiya jaata hai aur phir baaki records se cross-check: bina SPF ya DKIM wali DMARC policy, ek MX host chhodne wali MTA-STS policy, enforcing DMARC ke bina BIMI logo. Aapko 100 mein se score, letter grade aur har finding ka saaf-saaf fix milta hai. Sab kuch aapke device par parse hota hai; koi DNS query nahi hoti aur kuch upload nahi hota.

Features

  • Ek hi paste mein MX, SPF, DKIM, DMARC, MTA-STS, TLS-RPT aur BIMI records pehchanta hai
  • Zone-file lines, dig output, nslookup output aur seedhe TXT values padhta hai
  • 0–100 score, letter grade aur har finding ka likha hua fix deta hai
  • Records ko aapas mein cross-check karta hai: SPF ya DKIM ke bina DMARC, MTA-STS policy mein na aane wale MX hosts, enforcement ke bina BIMI
  • Galat naam par publish hue records pakadta hai, jaise _dmarc ki jagah root par DMARC
  • Duplicate SPF aur DMARC, +all, bade ip4 ranges aur chhoti DKIM keys flag karta hai
  • MX hosts se common mail providers pehchanta hai aur chhoota hua SPF include batata hai
  • Poori report ko plain text mein copy karein — ticket ya client ke liye

Email Domain Health Check kaise use karein

  1. “How to get these records” ke neeche diye dig commands chalayein aur unka output copy karein
  2. Output box mein paste karein; domain khud nikal liya jaata hai, ya type karein taaki har record ka publish-naam check ho
  3. Score padhein, phir har card kholkar findings dekhein, errors sabse pehle
  4. DNS host par records theek karein, TTL ka intezaar karein aur confirm karne ke liye dobara paste karein

Example

Input

3 MX records at Google Workspace · SPF with SendGrid ~all · DKIM 2048-bit · DMARC p=none

Output

Score 83/100, grade B — SPF pass · DKIM pass · MX pass · DMARC review: p=none only monitors

Har record maujood aur valid hai; grade sirf monitoring-only DMARC policy ki wajah se ruka hai.

Common errors aur troubleshooting

  • DMARC publish karne ke baad bhi not pasted dikhta hai. — DMARC sirf _dmarc.aapkadomain par, TXT record ke roop mein padha jaata hai. Bare domain par ya underscore ke bina dmarc par daala record kabhi nahi milta. Kai DNS panel domain khud jod dete hain, isliye host mein sirf _dmarc likhein.
  • SPF do records hone par fail dikhta hai. — Ek domain par ek hi SPF record ho sakta hai. Do hone par receivers permanent error dete hain aur SPF ko bilkul ignore kar dete hain. Saare include, ip4 aur ip6 mechanisms ko ek v=spf1 string mein milayein aur doosra delete karein.
  • DKIM check ko kuch nahi milta. — Verifiers <selector>._domainkey.<domain> dekhte hain, aur selector wo s= value hai jo aapke bheje asli message ke DKIM-Signature header mein hoti hai. Andaaze se likha selector khaali jawab deta hai; asli selector kisi message ke headers se copy karein.
  • Saare records hone par bhi grade B par atka hai. — DMARC policy none sirf monitor karti hai, isliye report DMARC ko review ke liye mark karti hai. Apni aggregate reports padhein, fail hone wale senders theek karein, phir policy ko quarantine aur antim mein reject par le jaayein.

Aksar pooche jaane wale sawaal

Email domain health check asal mein kya test karta hai?
Wo DNS records jinhe mail systems aapke domain par bharosa karne se pehle dekhte hain: MX (mail kahan receive hota hai), SPF (kaun se servers bhej sakte hain), DKIM (signing key), DMARC (jab ye fail hon to policy), aur optional MTA-STS, TLS-RPT aur BIMI. Har ek ka syntax aur baaki ke saath uska mel dono check hote hain.
Domain type karne ke bajaye records paste kyun karne padte hain?
Domain ka lookup karne ka matlab hota uska naam kisi bahari DNS resolver ko bhejna, aur ArrayKit aapka kaam aapke device par hi rakhta hai. Page par diye dig commands se paste karne mein kuch second lagte hain, aur isse wo records bhi check ho jaate hain jo abhi publish nahi hue.
Bulk senders se Gmail aur Yahoo kaun se records maangte hain?
Feb 2024 se dono bulk senders se, yaani apne users ko roz lagbhag 5,000 ya zyada messages bhejne walon se, SPF aur DKIM aur kam se kam p=none wala DMARC record maangte hain, jisme From domain inmein se kisi ek se aligned ho. Chhote senders bhi spam filtering se bache nahi hain.
SPF, DKIM aur DMARC ke upar MTA-STS aur TLS-RPT kya jodte hain?
SPF, DKIM aur DMARC saabit karte hain ki message kisne bheja. MTA-STS doosre servers ko kehta hai ki aapke domain tak sirf validated TLS se deliver karein, jo downgrade attacks rokta hai, aur TLS-RPT ke fail hone par aapko reports bhejta hai. Ye aapke domain tak delivery ko bachate hain, domain se nikalne wale mail ko nahi.
Paste karne ke liye DKIM selector kaise milega?
Kisi bhi mailbox ko message bhejein, uska original source kholein aur DKIM-Signature header dhoondhein. s= value selector hai aur d= domain. Aapke mail provider ka admin console bhi set kiye gaye selectors dikhata hai, jaise google ya selector1.
